UNITED STATES PATENT OFFICE.

JOHN B. HADAWAY, O1? SVI'AMIFSGOTT, MASSACHUSETTS, ASSIGNOR T0 UNITEDSHOE MACHINERY CORLPGRATION, O13 PATERSGN, NEW

NEW JERSEY.

Application filed September To all whom it may concern Be it known that1, JOHN B. HADAWAY,

a citizen of the United States, residing at Swampscott, in the county ofEssex and State of Massachusetts, have invented certain Improvements inSole-Edgelreating Tools, of which the following description, inconnection with the accompanying drawings, is a specification, likereference characters on the drawings indicating like parts in theseveral figures. This invention relates to machines having vibratingtools or irons employed in the manufacture of boots and shoes, as toolsfor burnishing, polishing, rubbing, shaping, pounding, or otherwisetreating the sole edges.

In machines of this character heretofore proposed it has been customaryto employ a tool having a single bed surface for operating on the soleedge and such machines are entirely satisfactory. when the marginalportions of the soles are uniform in thickness.

Most tools of the character referred to consist of single members andwhen they are constructed with the usual lips they are incapable ofoperating upon a sole edge which may slightly exceed the width oftheface of the tool between such lips.

I A particular object of the present invention is to provide an edgesetting tool the utility of which is not limited to operation uponmaterial having a limited maximum width, and to this end a specialfeature of the invention consists in a tool comprising apluralityof-inembers and having guiding jisto provide a sole edge setting toolwhich lips, said members being relatively movable to vary the width ofthe tool as a whole.

A'further object of my present invention will automatically accommodateitself to varying thicknesses of diiierent portions of the sole edge.

An important feature of this invention is a tool comprising a holder anda plurality of edge finishing irons yieldingly carried by the holder andso constructed and arranged that while the tool is adapted to operateproperly while in normal condition upon a sole edge of uniformthickness, yet

if a sole edge portion which is of different thickness is encountered,the tool as a whole Specification of Letters Patent.

will automatically adapt itself to such thickness as by spreading orwidening.

In the illustrated embodiment of the in vention, a holder is providedhaving a plural1ty of e lge finishing irons mounted side by side and inclose relationship, the irons being yieldiiigly supported by the holder.

While the invention is useful in various relations,- as, for example, inconnection with edge setting machines of a type which requires theoperator to shift the work manually along and in contact with thesetting tool, the illustrated embodiment of the invention is designedwith particular reference to machines of the automatic type such asillustrated and described in Letters Patent No. 1,0et8,l74, granted Dec.24, 1912, upon the application of F B. Keall.

'Wh en single tools are used in automatic machines of the typeillustrated in said patent, they are pivotally mounted on an axisparallel to the sole edge in order that the working face of the tool mayadjust itself tothe edge of the sole and operate upon all parts of it.The axis about which the tool swings passes through the middle of thebed of the tool.

Another important featureof the present invention resides in a finishingtool constructed andarranged so as to make it certain that all parts ofthe edge will be finished regardless of minor variations in thethickness of the sole edge.

Fi ure 1 of the accompanying drawings is a perspective view illustratingthe invention as applied to a machine of the type explained in thepatent hereinbefore referred to.

Fig. '2 is a detail side elevatiompartly broken out, of the preferredembodiment of my invention.

Fig. 8 is an elevation looking from the left of Fig. 2. 1

Fig. t is a view similar to Fig. 2 but illustrating a modification; and

F 5 is a broken out perspective view of the form of holder and its ironsshown in Fig. 4:.

The tood. carrier 12 which, it isto be understood, is to be mounted inthe machine to be vibrated in any well-known or pre ferred manner, isformed with a recess 13 (Fig. 2) above and below which are stopshoulders 14. Midway of the stop shoulders and extending transversely ofthe recess 13 the carrier is formed with a bearing 15-to serve as apivot for the irons 16 of which three areshown in the drawings. '1

do not limitmyself to this number, how

from that illustrated in the drawings. For. present purposes it issufficient to illustrate the upper and lower lips 20 as having the sameconfiguration.

Each iron he a leaf spring21, secured by a screw 22 passed into thecarrier 12,

bearing upon its upper or its lower edge- As shown by comparing Figs. 2and 3, the springs act alternately in opposite directions upon theironsso as to hold them nor? mally in position with their lips out'of lateralalinement so that the bed of the tool.

as a whole will automatically accommodate itself, as to width, to thewidth of the'sole edge operated upon.

Assuming that the sole, the edge portion of which'is indicated at 'S inFig. 2, is of justtherelative'width indicated in the figure,

the irons will retain the relative positions illustrated in Figs. 2and3. As work progresses along the sole, however, if a thicker portion ofthe sole edge is encountered, the 1rons automatically shift toward aposition where their lips will be in lateral alinement,

without, however, causing any portion of the acting face of either ironor tool to project beyond the acting face of an adjacent iron or tool.In other words, it may be stated that the tool as a whole has alaterally expansible operating surface all portions of which, betweenthe lips 20, remain in the original operating surface during allmovements of the members 16 relatively to each other. As soon: as anysuch thicker portion. of the sole edge has been passed, the springs 21automatically return the irons toward or to their normal positions whichare determined by the stop shoulders l l. 7

I do not limit myself to providing a pivw otal connection between theirons and the carrier; For instance, as shown in Figs. 4 and 5 the lronsmay be mounted to shde.

In said figures the tool carrier is indicated at 30, said carrier havinga plurality of recesses 31 in which are transversely mounted rolls- 32.Vertical guideways 33 in the side walls of the recesses 31 are engagedby rib,

performed.

ing lips 35. Springs 36 secured to the carrier by screws 37 bear uponthe sliding irons to hold them normally in the relative positionsindicated in the drawings. In the 'op eration of a machine havinga toolof the character illustrated in Figs. 4 and 5, the automatic shifting ofthe irons under the control of the sole edge itself is effected in thesame manner as hereinbefore described in connection with Figs. 2 and 3.

In Fig 1 I have illustrated certain parts of the machine of the Keallpatent herein before referred to, said Fig. 1 illustrating.

said parts substantially as they are illustrated in Fig. 1 of the saidpatent. To facilitate an understanding of the particular utility of thepresent invention in a machine ofthe 'Keall type, the parts have thessame aid parts include two feelers 50, 52, the feeler a rockshaft 58.The lever 60 performs an operation unnecessary to describe in thepresent case. The'feeler 130 is carried by a rockshaft 138 and thefeeler 142 is carried by therockshaft 1456, another arm 14A of which '50being actuated by alever 56 carried by is connectedto the tube 134:through which the rod 136 passes. Ihe feeler 52 is operated by the lever7 6 and the latter is connected with the rod 80 extending through thetube 62. Since the particularoperation of these feelers and how theycontrol the automatic operation of the machine of the Keall patent hasnobearing upon the present invention, reference may be had'to the saidpatent for a complete description thereof. 7

In the form of invention illustrated in Figs. 2 to 5 inclusive, thesprings act to normally maintain the irons with their lips V out oflateral alinement so that the bed portions of the irons willact'properly along the sole edge regardless of suchordinary variationsin thickness of the sole edge as is liable to occur. 7

It is to be understood that]: do not limit myself to the particularshape of the acting faces of the irons illustrated since the irons maybe shaped to best suit the work to be Having noii claim r 1.
